Description
This setting is only active if USB Functions above it is Disabled. This setting
allows you to Enable or Disable the USB 2.0 controller in your system.
This option allows you to enable the use of Legacy USB devices. If this option is

Description
If Compatible is selected, this sets SATA#1 to legacy compatibility mode.
Selecting Enhanced sets SATA#1 to native SATA mode. The options are
Disabled, Compatible and Enhanced.
This setting allows you to select the drive type for SATA#1. The options are IDE,
and AHCI.
This setting allows you to select the time out value for detecting ATA/ATAPI
devices in your system. Options include values for 0, 5, 10, 15, 20, 25, 30 and 35
seconds.
This submenu displays the type of drive and contains IDE Master/Slave settings.
This setting specifies the type of device connected to the system. Options
include Auto, CD/DVD and ARMD.
This setting allows you to enable/disable LBA Mode. Options include Disabled
and Auto, which enables LBA mode if the device supports it and the device is
not already formatted with LBA mode disabled.
Block mode boosts IDE drive performance by increasing the amount of data
transferred. Only 512 bytes of data can be transferred per interrupt if block mode
is not used. Block mode allows transfers of up to 64 KB per interrupt.
Select "Disabled" to allow the data to be transferred from and to the device one
sector at a time. Select "Auto" to allows the data transfer from and to the device
occur multiple sectors at a time if the device supports it. The options are Auto
and Disabled.
PIO (Programmable I/O) mode programs timing cycles between the IDE drive
and the programmable IDE controller. As the PIO mode increases, the cycle time
decreases.
The options are Auto, 0, 1, 2, 3, and 4. Select Auto to allow BIOS to auto detect
the PIO mode. Use this value if the IDE disk drive support cannot be determined.
Select 0 to allow BIOS to use PIO mode 0, which has a data transfer rate of 3.3
MBs. Select 1 to allow BIOS to use PIO mode 1, which has a data transfer rate of
5.2 MBs. Select 2 to allow BIOS to use PIO mode 2, which has a data transfer
rate of 8.3 MBs. Select 3 to allow BIOS to use PIO mode 3, which has a data
transfer rate of 11.1 MBs. Select 4 to allow BIOS to use PIO mode 4, which has a
data transfer rate of 16.6 MBs. This setting generally works with all hard disk
drives manufactured after 1999. For other disk drives, such as IDE CD-ROM
drives, check the specifications of the drive.
Selects the DMA Mode. The only option is Auto
